Sen. Pat Toomey (R-Pa.): A Club for Growth-conservative, Toomey is practically a moderate by 2010 standards. He won't even go to Washington to fight against fluoride in your drinking water or block the NAFTA superhighway in your backyard. But few candidates capture the GOP's commitment to unlearning the lessons of the last decade like Toomey. Toomey cut his teeth as a derivatives trader on Wall Street, engaged in high-risk interest rate swaps, and then later, as a congressman, used his influence to push for more deregulation. As Nick Baumann reported, "Shortly after he was elected to Congress in 1998, a trade magazine rejoiced that "now the derivatives industry can claim representation by one of its own."
